EL817(S)(TB)-V Typical application Circuitry

EL817(S)(TB)-V

Optocouplers, sometimes referred to as opto-isolators, are electronic devices that communicate electrical impulses between two isolated circuits by light. A device of this type is the EL817(S)(TB)-V. It usually comprises of a phototransistor and an infrared LED that are encapsulated so that the light from the LED can reach the phototransistor but the input and output are electrically isolated.

Application Scenarios

EL817(S)(TB)-V is commonly used in situations where electrical isolation is necessary for safety reasons, to prevent ground loops, or to protect sensitive electronics from high voltage spikes. Common applications include microcontroller interfaces, signal isolation in communication systems, power supply circuits, and digital logic circuits.

Parameter Features

The EL817(S)(TB)-V has several key features that make it suitable for a wide range of applications, including a high isolation voltage (typically several thousand volts), a Current Transfer Ratio (CTR) that denotes the efficiency of the optical coupling, and a relatively wide operating temperature range. The device is designed to offer fast response times, making it suitable for high-speed signal isolation.

Circuit Connection Example: Microcontroller Interface Isolation

In a microcontroller interface isolation application, the EL817(S)(TB)-V can be used to isolate control signals between a microcontroller and an external device, such as a motor driver or another microcontroller.

- Power Supply to LED: Use a current-limiting resistor to connect the internal LED's anode to a microcontroller digital output pin. The LED's cathode is linked to the ground. This setup allows the microcontroller to turn the LED on and off, thereby transmitting digital signals optically.

- Phototransistor Output: The emitter of the phototransistor is linked to the isolated circuit's ground, and its collector is connected to the positive supply voltage via a pull-up resistor. The phototransistor conducts when the LED is on, enabling the signal to cross the isolation barrier.

- Current-Limiting Resistor: A current-limiting resistor is connected in series with an LED in order to protect it from damage and regulate the current passing through it to appropriate levels.

- Pull-Up Resistor: A pull-up resistor is connected between the collector of the phototransistor and the positive supply voltage to ensure that the output signal is at a defined voltage level when the phototransistor is not conducting.

When designing circuits with EL817(S)(TB)-V, it's important to consider the current and voltage requirements of the LED and phototransistor to ensure proper operation. The value of the current-limiting resistor for the LED should be chosen based on the desired current through the LED and the supply voltage. Similarly, the pull-up resistor should be chosen to provide the correct logic level voltage at the output while allowing sufficient current to flow when the phototransistor is conducting. Additionally, the isolation voltage rating of the optocoupler should exceed the maximum voltage difference that might appear across the isolation barrier to ensure safety and reliability. It is important to adhere to proper PCB layout techniques in order to preserve the electrical isolation.
